We have already demonstrated the way of photo referencing relatively an existing image or vector .Next step is data extraction from the imagery, for example – at address plan forming. It is no secret that address plans (as well as navigation charts) are somewhat conventional. Data completeness and quickness of the work are main requirements at their forming. Exact positioning of objects usually fades into the background.

Well, it remains up to you to select accuracy of object positioning - Easy Trace provides all necessary means for it.And the speed of decoding is shown in this video:

The video is based on a record of actual work. All operations of scaling, navigation in the photo, and object forming are shown in real time.

The following new features of tools are used at vectorizing:

Orthogonalizing Tracer:

- dynamic scaling is provided for manual input of turning points. Easy Trace automatically scales up the working window at point input and thus enables exact positioning of the cursor. You may keep the scale for input of a series of points at a site of complex line form.

Rectangular Tracer:

- capture of object copies and their one-click placing are applied; - automatic orientation of rectangles along object edges / long lines is applied ; - quick change of an object copy’s rotation angle after placing is added; - change of an object copy’s size by mouse wheel is added; - Guides may be specified now that help you to place a number of objects along a line;

Editor:

- "orthogonal" move of adjacent edges in ortho-objects is provided at capture and move of their common vertex. For example, walls will be shifted when you shift a corner of the building.
